WebJul 8, 2024 · Process steps In order to influence the hardness and the strength of a steel, a special heat treatment, called quenching and tempering, has been developed. Quensching and tempering can be … Heat treating (or heat treatment) is a group of industrial, thermal and metalworking processes used to alter the physical, and sometimes chemical, properties of a material. The most common application is metallurgical. Heat treatments are also used in the manufacture of many other … See more Metallic materials consist of a microstructure of small crystals called "grains" or crystallites. The nature of the grains (i.e. grain size and composition) is one of the most effective factors that can determine the … See more Proper heat treating requires precise control over temperature, time held at a certain temperature and cooling rate. With the exception … See more Usually the end condition is specified instead of the process used in heat treatment. Case hardening See more Furnaces used for heat treatment can be split into two broad categories: batch furnaces and continuous furnaces. Batch furnaces are … See more The specific composition of an alloy system will usually have a great effect on the results of heat treating. If the percentage of each constituent is just right, the alloy will form a single, continuous microstructure upon cooling. Such a mixture is … See more Complex heat treating schedules, or "cycles", are often devised by metallurgists to optimize an alloy's mechanical properties. In the aerospace industry, a superalloy may undergo five or more different heat treating operations to develop the desired … See more • Carbon steel • Carbonizing • Diffusion hardening • Induction hardening • Retrogression heat treatment See more

Basic Principles and Design Guidelines for Heat Treating of Steel
WebNov 15, 2024 · Heat treatment is a heating and then cooling process using predefined methods to achieve desired mechanical properties like hardness, ductility, toughness, strength, etc. It is the combination of thermal, … WebT (Time) T (Temperature) T (Transformation) diagram is a plot of temperature versus the logarithm of time for a steel alloy of definite composition. It is used to determine when transformations begin and end for an isothermal (constant temperature) heat treatment of a previously austenitized alloy. When austenite is cooled slowly to a ... WebPure iron, wrought iron, and extremely low-carbon steels have very little hardening properties and are dif-ficult to harden by heat treatment. Cast iron has limited capabilities for hardening. When you cool cast iron rapidly, it forms white iron, which is hard and brittle. In plain carbon steel, the maximum hardness ob-tained by heat treatment ... chinese medical center swab test
